About the only think I might suggest would be a neck sizing bushing die. If this will be your only 44-77, a bushing die will work well and will keep from overworking your brass. As hard as it is to come by, you want to work it as little as possible. I have made 2 of them, one that will work on 2.1" cases up to the 44-77 and maybe a bit longer. You can make your own bushings and adjust the size so that you size the neck just enough to hold the bullet. In the same die you can put a decaping rod, a compression plug and an expander. Then you can make a spacer and a taper crimp bushing as well. I made my first from steel and it works quite well. The second one I made up out of aluminum and its for a much shorter case and I have only used it just a little but other than forming the case necks down from 45-70 brass there isn't that much pressure on the die body so I think it will work just as well. The last bushing I made up I used 8620 and it worked ok but needs to be hardened so that it doesn't pick forign material and scratch the cases.
things to think about.
